Rajul. The 2 leads shown are genuine Multiplex. The grey lead ( 5 pin ) is around 8 years old and the black lead ( 7 pin ) is about 6 months old. In the past the TX's load up immediately in the same way the AFPD controller does. I borrowed a AFPD controller and it worked fine and my computer repair man loaded my AFPD disk to one of his computers but he was unable to use the sim using mt TX. I have a 12 and a 16 channel MPX TX but use the 12 channel for the simulator. I set up a seperate model in the model memory for the simulator models. The socket in the back of the TX is 7 pin. I will be away for the weekend flying IMAC. [img]P1030048.JPG[/img] [img]P1030049.JPG[/img][img]P1030050.JPG[/img] Oops - no photos.
